Nearly a fifth of university students are unhappy with their degree courses, a major poll has revealed.

The annual National Student Survey found the happiness with the quality of courses in England has stalled this year.

Some 19% of full-time, final year undergraduates in England said they were not satisfied with the quality of their course this year, the same proportion as last year.

Students at Buckingham University, a private institution, were happiest with their course, giving an overall rating of 95%.

A number of institutions in England were given overall satisfaction ratings of 93%, including the Open University, Oxford and Medway School of Pharmacy. Some 91% of students taught at Cambridge were happy with their courses.

Overall, 81% of full time undergraduate students at universities in England were satisfied with the quality of their courses, the survey, published by the Higher Education Funding Council for England (HEFCE), revealed.

Taking into account students studying at all types of universities and further education colleges in England, the satisfaction rate was 82%.

Students were asked about every aspect of their university experience, including questions on teaching, assessment, support and resources. Satisfaction with teaching was high, with 87% of full-time students in England saying staff were good at explaining things.

Around four-fifths (79%) said staff made the subject interesting, and a slightly higher proportion (84%) said staff were enthusiastic about what they were teaching. But more students raised concerns about feedback and comments on work.

More than two-fifths (41%) said they did not think they had received prompt feedback on their work, while only 58% agreed that feedback had helped them to clarify things they did not understand.
